IMPROVEMENT IN COAL-CARS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom may concern:

Be it known 'thatI, THOMAS MoOnonr, of Fayette City, county of Fayetteand State of Pennsylvania,- have invented an Improvement in Inclinedgoal-Cars; and I do hereby declare that the following 18 a full, clear,and exact description of the same, reterence. being had to the annexeddrawings and to the letters of reference marked thereon making part ofthis specification, in which- Figure 1 is a side elevation of a part'ofan inclined railway, showing the coal-car on it, with the tripping cleator cam G on the side of it.

Figure 2 is a top view of fig. .l. Figure 3 is a plan of the rotatingbottom or wicket. Figure 4 is aside elevation of the tripping-lever. Ais the division for the dust or coal slack. B is the rotating bottom orwicket of division A. C is a clcat or cam on the side of the rail, overthe curved surface of which the forked lever d d must pass.

D is the handle of the forked lever (1 cl, tobe opcratcd by hand, whennecessary.

E, the rails of the inclined track. F, the main coal-division of thecar. a a, the wheels-of the car which travel in the grooves e e. b, theshaft of the rotating bottom or wicket B. i I), the nut fastening thelever on shaft 1). c, partition between the dust or slack and coal. 1! dthe arms of forked tripping-lever. d, t e spring clamp confining leverD. e c, grooves in rails.

The nature of this invention consists in the combination ofa trippingdevice on the end of the shaft of a rotating bottom or wicket ofacoal=car, operated by a curved cleat or cam on the side of the railover which the car passes in its descent from the coal-bank, said cleator cam being located at the point where the dust or coal, &c., may berequired to be dropped, and the shape of the elect or cam is so madethat the curve of the lever, in passing over it,willbemadeto turn thebottom or wicket of the coal-car to dump its contents.

For convenience, more than one wicket may be used, so that they may bemade narrow, so as not to strike against the cross-ties of the railroad.

The shaft?) of the rotating bottom B is extended at one end, and hasfastened to that end a crooked lever, d d, by a nut and near the side ofthe car; also a straight lever, D, which lever is kept in position bythe frictional bearing of a spring clamp,d", fastened to the side of thecar.

The bottom B is made of metal or other suitable material, and turnsfreely by its axis 1) in journal boxes on the sides of the car.

The distance ofthe crooked leverfl d from the side, is suited to thewidth of rail, so that it will passimmediately over the cleat or cam Gon the outside of the rail.

The operation of this device is very evident; as the car descends, thecleat causes thelever d d to be tilted up, as seen in fig. 1, and thebottom B rotates with it and the contents of the division A areimmediately dropped.

Having thus fully described this invention, WVhat I claim, and wish tosecure by Letters Patent of the United States, is-

In a wicket bottom slack or dust inclined coal-car, the combination ofthe curved lever d d on the end of the axis of a rotating bottom, B,with and oper- Witn esses V W. E; FRAZER, Jr., HARVEY B. FRY.
